NThis post is all over the place, conflating plastic leeching, throwing out vague concerns and then panicking that there must be NO standards. To really answer it would require giving someone a comprehensive education in food safe materials science, likely fitting though many dearly-held misconceptions along the way. Anyone who thinks that plastic touching food is a health risk must have all their meals brought to them on a plate, and have no idea how food is delivered to stores or packaged for sale.
